How does pyrrolidine work, you know?

Pyrrol and its methyl substituted homologues are present in bone tar. Colourless liquid. The boiling point is 130~131℃ and the relative density 0.9691 (20/4℃). Easily soluble in water, easily soluble in organic solvents such as ethanol and ether. Pyrrol can turn black under the action of traces of oxygen; the flaky reaction results in red; it polymerizes to pyrrolred under the action of hydrochloric acid; it is generally unstable to oxidizing agents. A substitution reaction may occur, mainly in the 2- or 5-position. At 15°C, the pyrrole is nitrided into acetic anhydride with nitric acid to obtain 2-nitropyrrole, and the yield is not high, and a part becomes a resinous substance. Pyrrol is formally a secondary amine, but slowly dissolves into dilute acid; The hydrogen at the ring is replaced by an alkyl group and the basicity increases, allowing insoluble salts to be formed. Pyrrol may form salts with picric acid; It can also be reduced to dihydro and pyrrolidine.

pyrrolidine is corrosive and inflammatory. Slightly flammable, vapours form explosive mixtures with air. Burning produces irritating or toxic fumes. The chemical properties are alkaline, react with acids to salts and react violently with oxidants.
